Abstract

Creativity could be interpreted as a person's cognitive abilities in solving problems by bringing up new ideas. The problems of students’ math achievement lows is math presented as finished product, ready to use, abstract and taught mechanistic. This case can be lead to the creativity of the less developed students because students are not given the opportunity to think and use theirs ideas in solving mathematical problems. Problem Based Learning Model is a learning model that emphasizes the concept and information outlined from the academic discipline. The purpose of this study is to analyzed students’ creativity in solving mathematical problems through Problem Based Learning model (PBL) in class VIII-1 MTsN Model Banda Aceh. Data qained based on the students’ worksheet in groups. The data acquisition is categorized into 5 levels (highest level 4 and lowest level 0) which is analyzed descriptively. The results is three groups were at level 4 with very creative categories, one group is at level 3 with creative category and another group is at level 2 with deeply creative enough category. To the conclusion is PBL model could cultivate the students’ creativity in solving mathematical problems.

Abstract

The purpose of this study was to explore students' attitudes toward statistics (ATS) based on the beginning and the end of learning, based on differences in fields of study, and examine its relationship with statistical acheivement. ATS was measured by an attitude instrument, namely The Survey of Attitudes toward Statistics (SATS) which consists of six dimensions (affective, cognitive competence, difficulty, value, interest, effort). Research respondents were undergraduate students who took lectures on statistical recognition that came from at one of the universities in South Sumatra. The results of the descriptive analysis showed the variation of ATS in each dimension of attitudes classified into positive, neutral, or negative attitudes. Although there are variations in the response of student attitudes in each dimension, but the results of statistical tests have not been able to show differences in attitudes between the beginning and the end of learning in each dimension. The differences in attitudes between the beginning and the end of learning that are statistically significant are in the dimensions of affective, value, and effort. The difference in the field of student science shows the difference in ATS, but only in the dimension of value. This study does not have enough evidence to state that there is a significant relationship between student attitudes to statistics and the results of learning statistics.

Abstract

This research was a descriptive research. Description of research result was presented quantitatively and qualitatively. Subjects of the research were 30 (thirty) 8th graders of SMPN 10 (State Junior High School) in Semarang, Indonesia. Data were collected through tests, documentation, observations, and interview. Student answers documents were observed and analyzed with SOLO Taxonomy guidance. The objective of the study was to analyze and provide an interpretation of students abstract reasoning level in cognitive development based on intended learning outcomes. The result of findings from students’ answers basically showed that students' abstract reasoning on the lower, middle and upper level, was alike to stages of structure complexity improvement. There were two main changes from concrete thinking to abstract thinking: quantitative stage (uni-structural and multi-structural) occurred first, as the number of details in student responses increased and then changed qualitatively (relational and extended abstract) because the detail was integrated into a structural pattern.

Abstract

This research aims at developing local instruction theory for learning combinations by using Realistic Mathematics Education (RME). This research uses a design research approach, Hypothetical Learning Trajectory (HLT), developed from a series of activities to obtain a better understanding about combinations at Senior High School (SHS) students. Theoretical development is supported by an interactive process in designing learning activities, conducting teaching experiment and conducting retrospective analysis to contribute to combinations of Local Instruction Theory (LIT). An understanding of combinations emerges and develops during classroom learning activities. Qualitative analysis of teaching experiments shows that by using local instruction theory teaching materials that characterize RME students are able to develop their understanding about a combination.
